Which outcome occurs during rapid solidification of undercooled molten metal?

💡 Explanation

During rapid solidification, particularly with undercooled melts, latent heat evolution becomes a limiting factor because the heat released by the phase transition cannot dissipate quickly enough, slowing crystal growth. Therefore, the evolution of the latent heat limits crystal growth, rather than segregation which becomes limited, decreases in viscosity, or decreased nucleation rate.
